•
Use the Covermeter to locate and measure the minimum area of cover within each grid cell, or
the cover to the reinforcement bar nearest to each grid-point, depending upon your survey
procedures.
•
Store the results in a grid batch corresponding to the grid of squares (press [
] to enter a
reading while the batch is open).
•
If required, create a separate batch
of the same name
configured for half-cell and store
corresponding half-cell potential measurements for each location. This allows the batches to
be grouped for production of reports which combine cover and half-cell readings using
CoverMaster
®
software - see “CoverMaster software” on page 53.
